In Virginia, 120 lame dogs were tested for arthritis and Lyme disease. The results showed that 42 of the dogs had Lyme disease,

miskamm [114]

Answer:

The number of dogs that had both Lyme disease and arthritis is 18

Step-by-step explanation:

Let x represent dogs that have both Lyme disease and arthritis

Dog with only Lyme disease = 42 - x

Dog with only arthritis = 96 - x

The sum of the 3 category should give 120

x + (42 - x) + (96 - x) = 120

Collect like terms and solve

x - x - x + 42 + 96 = 120

-x + 138 = 120

138 - 120 = x

x = 18

Dog with only Lyme disease = 42 - x = 42 - 18 = 24

Dog with only arthritis = 96 - x = 96 - 18 = 78

Therefore, the number of dogs with both Lyme disease and anthritis is 18.

A normal distribution has \mu = 65 and \sigma = 10. Find the probability that the average score of a group of n = 4 people is be

Kipish [7]

Answer:

The probability that the average score of a group of n = 4 people is between 70 and 75=0.13591

Step-by-step explanation:

We are given that

$\mu=65$

$\sigma=10$

n=4

We have to find the probability that the average score of a group of n = 4 people is between 70 and 75.

$P(70$

$=P(\frac{5}{5}$

$=P(1$

$=P(Z$

$=0.97725-0.84134$

$=0.13591$

Hence, the probability that the average score of a group of n = 4 people is between 70 and 75=0.13591

What is the y-value of point A? On a coordinate plane, point A is 6 units to the right and 1 unit up.

Sergio039 [100]

Answer:

Step-by-step explanation:

Points on a coordinate plane are written as (x,y) coordinates. The vertical axis is the y axis. If your point is "one unit up" its y-value is 1. (The horizontal axis is the x-axis. The x-value is 6.)
